To all whom t may concern.'

Be it known that I OSCAR L. SMITH, a citizen of the United tates, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented an Improvement in F iber-Shipping- Case- Sealing Machines, of which following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to machines for sealing fiber or pasteboard shipping cases and more particularly to mechanism for securing the overlapping flap members of the casing' by metallic fastenings.

In view of the cost of boxes creases formed of woodor like material, and the time necessary in the constructionof such form of cases, it has become more and more desirable to employ fiber shipping cases which are of a knock-down character and usually formed of blanks which can be quickly assembled.

The use of these fibrous or pasteboard shipping cases has created a demand for a reliable metallic seal for joining the adjacent edges. The main dificulty in such metallic seal is encountered after the case has been filled and the adjacent edge portions of the flaps are to be connected together. An important feature of the present invention, therefore, consists of novel means for-reliably supporting the adjacent edges of the flaps of a fiber shipping case and maintaining them in proper co-relation during the driving 'of metallic fasteners, such as rivets, or the like.

In carrying this feature of the invention into practical effect the adjacent edges of -the flaps to be connected by the metallic fasteners are guided and supported by a rigid member containing an anvil over which the flaps of the fiber shipping case are moved during the driving of the fastenings. More specifically considered, the guide for the adjacent edges of the flaps comprises a rigid goose-neck between the overlapping members` of which one of the edges passes whiler the other edge is supported by an exteriorcportionof the gooseneck. Preferably the ber sealing case is supported on a table or suitable rest and is moved thereon relative to the goose-neck and the fastener-inserting mechanism durlng the sealing operation. In the illustrated form of the invention the fasteners are shown as rivets which pass through the overlapping adjacent edges of the fiber seal flaps and are clinched on the under-side of the underlapping flap, but certain features of the invention arel applicable to other forms of metallic sealing machines.

In the drawings: I

Fig. 2 is an enlarged detached detail showing the form of guide or goose-neck, the view being taken at the front and delivery side thereof;

Fig. 3 is a perspective view looking from g the'left and front of the machine;

Fig. 4 is an enlarged detail front elevation showing more particularly the guide or goose-neck and the cooperating rivet driving means;

F ig. 5 is a side elevation looking from the left of Fig. 3 and showing the rivet driven through the overlapping edges of ad`acent flaps and clinched;

ig. 61 is a sectional detail showing the The rivet drivin machine may be of any usual or desired c aracter and 1n the presen t invention comprises a base portion 1 -from `which rlses the column 2 surmounted manner of supporting the goose-neck hang-lA lever 6 may be actuated under'manualcon# I trol. Mounted on a bracket 9 extending from the arm 3 is the shaft 10 carrying the belt pulley 11 which may be driven from any suitable source of power such, for instance, as the lineshaft. Connected to the lever 6 is a link 12 which may be actuated at desired intervals by suitable means driven from the driving shaft 10 under controlo? the treadle 13. IThe treadle 13 is pivoted v to the machine frame' at le and has al1-erm 15 pivotally connected at 16 to a link 17 for controlling the operative or inoperative relation of the lilik 12 and its actuating means. The parts heretofore described may be of usua. and well understood character, andl as they foim no essential part of the present invention so far as details are concerned, further description t-hereof appears unnecessary. j

A spring 18 connected to the treadle arm 15 serves normally to depress the rod 17 and lift the treadle 13, the construction being such that upon 'depression of the treadle 13 the rod- 17 is raised to throw into operation the driving mechanism.

The lever 6 is connected at 19, Fig. 3, to the driver 20 which is ruided'in the head 21. Slidably mounted 1n the head 21 adjacent the driver is the slide 22, the lower end of which carries the nose 23 into which the rivets are delivered onel by one by a .suitable separating device, common in this class ot' machines. The slide 22 is normally held raised by a spring 24. one end of which is connected to a pin 25 extending from the slide and at the other ,end to a pin 26 j extending from the head 21, the construction being such that when the driver 20 is raised or inoperative, the spring 24 lifts the nose 23 into position adjacent to tbc chute 5 for receiving a staple. rThe inachine thus far described contains nothing essentially new and is convenientlyy illustrated herein as Ashowing one good form of means for driving rivets. Mounted on and secured to the arm 3 is a hanger 27 preferably provided with ./"shoulders 28 which engage flanges formed in the overhanging portion of the arm 3. One or more bolts 29, Figs. 3 and 6, serve to maintain the hanger 27 in rigid connection with the arm The hanger 27 has secured to it the guide or goose-neck by which the adjacent and overlapping edges of the flanges to be sealed are supported and guided. In the present instance the hanger 27 is provided with a recessed portion 30, Fi ceived a corresponding' shaped lug 31 extending rearwardly from the goose-neck 32, and a bolt 33 rigidly secures the goose-neck 32 to the hanger.

The guide, or goose-neck 32 extends downwardly and frontwardly, as indicated in Fig. 2, the downward and frontwardl eX- tending portions thereof, as at 34, eing preferably inclined towards the front edge portion of the hanger at 35 where the hanger turns to forni the lower member 36 of the goose-neck. In order that the nose 23 and the driver may descend and carry the a'djacent superposed edges of the overlapping flaps into substantial contact, the goose-neck l -is .recessed or cut away`as at 37, and the lower member 36 of the goose-neck, adjacent the cut away portion, carries an anvil 38,

o. 5, in which is re-l preferably formed as `a removable steel block to resist the downward thrust of the driver and etfecta clinch of the rivet.

' As best indicated in Figs. 2,3 and 4, the upper supporting surface 34 of the gooseneck inclines from the left or entrance of the work, towards the riveting point at lthe right or delivery end of the goose-neck, and both portions 34 and 36 of the goose-neck provide unyielding and rigid guidesor supports for the adjacent edges of the overlapping flaps. This is well indicated in Fig. 4,@ wherein the upper flap a, of the fiber ship-V ping ease, is shown resting upon the upper' surface 34 'of the goose-neck, while the lower or underlying iiap b of the tibershippingcas'e enters the recess 39 between the upper surface of the lower member 36 and the lower surface of the upper member or portion 34 of the goose-neck. By reason of the incline of the supporting surface 34 of the gooseneck, the upper overlying flap a. is directed downwardly towards the lower or underlying flap as the two i'laps approach the riveting point, as indicated in Fig. 4, the construction being such that when a rivet is driven, as indicated by dotted lilies in Fig. 4, and full lines in Fig. 5, the overlying flapI is bent downwardly towards and into contac-t with the lower flap.

When a fiber shipping case is to be scaled by rivets in accordance with the present invention, the leading edges c of the overlapping flaps of the shipping case (l, are introduced to the guide or goose-neck by passing the lower sealing flap edge into the space 39 of the goose-neck so that the lower member 36 of the goose-neck travels inside of the shipping case above the contents thereof` and the overlapping flap (n is introduced above and uponthe surface 34. The treadle is then depressed and a rivet e driven, its endsbeing clinched by the anvil 38, as indicated in Figs. 4 and 5; The shipping case is then advanced a desired distance and al1- other rivet driven, and so on throughout the entire length of the overlapping edges to be united.

It is convenient to support the shipping' `case during the sealing 'operation upon a Itable or support, and in the present instance the table 40 1s mounted upon` a sleeve 41 into which projects the threaded post 42 mounted adjustably in the machine frame at 43. The sleeve 41 preferably carries a lug or key 44 which travels in a suitable slot or guide 45 on the threaded post 42. the

construction being such that as the table is raised and lowered, it will maintain its position without rotation. Loosely mounted on the sleeve 41 is a threaded adjusting collar 46 adapted to engage the threaded post 42, the construction being such that by rotation of the collar 46 the sleeve 41 and, perforce the table 40, may be raised or lowered into convenient position as dictated by the size of the shipping case to be sealed. The threaded post 42 may be held adjustably to the machine frame by a set screw 47, or otherconvenient means.

From the construction described it will be apparent that when the upper and lower adjacent edges of overlapping flaps of the sealing case are associated with the gooseneck, as hereinbefore described, the scaling case ma be moved upon the table 41 progressive y after each drive of a rivet, the lower rigid member 36 and the anvil 38 at such times traveling on the inside of the shipping case below the lower flap The present invention has been described i more particularly with reference to a suitable driving machine because in practice it has been found that staples' driven through overlapping `fiaps and clinched by the anvil afford a suitable permanent and secure metallic fastening for the adjacent edges of the overlapping flaps, but it is to be understood, of course, that other forms of fastenings may be driven'without departing from the true scope of the present invention as pointed out in the claims.

F romthe described embodiment of the in-.

vention it will be understood that the gooseneck guide oriiap support is secured adjacent the fastening inserting mechanism and that a part extends downwardly and transversely of and under one of the sealing flaps and that another part, which constitutes the anvil support, extends transversely in the opposite direction beneath the other flap and within the shipping case, so that as the shippin case is fed past the fastening inserting mec anism the two transversely extending por'tions enter the case from above 'and pass between or separate the two fiaps to be sealed. The anvil being rigid and rigidly held from the machine frame presents a reliable clinchin means for the rivets as the shipping case 1s moved past the goose-neck.
